One of the first to spread Manicheism in the Christian Orient. He was probably a Mesopotamian, and introduced the heresy into Eleutheropolis (Palestine). The Manichaeans were sometimes called after him Acuanitae. St. Epiphanius (Adv. Haer., lxvi, 1) calls him a veteranus, i. e. an ex-soldier of the empire, and fixes his propaganda in the fourth year of the reign of Aurelian (273).
